Reading over internet i had found that whole batch of E520 produced in second half of 2011. had issues with eeprom (this one is from 2011.) and that they behave like mine E520 (no power, completly dead). So i took the eeprom out (MX25L3206) and read its content to check if it's alive. And i was able to read it ... Now the problem is that i don't know if eeprom content is OK.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

please patch my bios dump dudes..

Model : lenovo e520 uma

hello, pressing on button does not light up, on the button there are 2.9v that go to zero by pressing the button, randomly making measurements on Q6001 I realized that by grounding pin 3 RTC_AUX_S5 the pc starts up and works but it does not turns off, the rtc battery is ok, the junctions of Q6001 measure 350ohm, it seems a bit low, what do you think?

thanks
